| + | ====== Special Bits ====== | ||
| + | ===== Select Bit ===== | ||
| + | This bit toggles with every read, and is returned as the high bit. Normally the controller uses this to select between two sets of buttons, but custom controller hardware could use this to clock arbitrary data out. | ||
| + | |||
| + | ===== Extra Button ====== | ||
| + | Accessible only by modding a physical GameTank, not exposed to front 9-pin port. | ||
| + | Could be used for GameTanks in custom installations such as a coin slot switch in an arcade cabinet. | ||
